Numerical Analysis of Supersonic Film Cooling in Supersonic Flow in Hypersonic Inlet with Isolator
Advances in Mechanical Engineering, 2014 Supersonic film cooling is an efficient method to cool the engine with extremely high heat load. In order to study supersonic film cooling in a real advanced engine, a two-dimensional model of the hypersonic inlet in a scramjet engine with supersonic ...

Improving Euler Computations at Low Mach Numbers [PDF]
International Journal of Computational Fluid Dynamics, 1996 This paper consists of two parts, both dealing with conditioning techniques for low-Mach-number Euler-flow computations, in which a multigrid technique is applied. In the first part, for subsonic flows and upwind-discretized linearized 1-D Euler equations, the smoothing behavior of multigrid-accelerated point Gauss-Seidel relaxation is investigated ...

Redox‐schaltbare Poly‐Lewis‐Säuren für die kontrollierte Freisetzung basischer Gäste
Angewandte Chemie, EarlyView.In dieser Arbeit werden redox‐schaltbare Poly‐Lewis‐Säuren auf Basis von Dibenzo[a,e]cyclooctatetraen vorgestellt, deren Reduktion zur Planarisierung, π‐Systemerweiterung und damit geschwächter Lewis‐Acidität führt, was eine kontrollierte Freisetzung von Basen‐Gästen ermöglicht.

Low-speed aerodynamic performance of 50.8-centimeter-diameter noise-suppressing inlets for the Quiet, Clean, Short-haul Experimental Engine (QCSEE) [PDF]
Two basic inlet concepts, a high throat Mach number (0.79) design and a low throat Mach number (0.60) design, were tested with four diffuser acoustical treatment designs that had face sheet porosity ranging from 0 to 24 percent for the high Mach number ...

A Relaxation Scheme for the Simulation of Low Mach Number Flows [PDF]
, 2017 A scheme for the simulation of inviscid flows with low Mach number is derived. The scheme is built on a relaxation system and it is based on a linear implicit time discretization. The advective part is discretized by a convex combination of upwind and centered schemes, in order to recover the correct limit when the Mach number goes to zero.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Chemical facilities storing large volumes of flammable liquids close to residential areas pose severe fire‐and‐explosion hazards that can escalate into disasters. In this study, a tank farm located within Istanbul's city limits is examined to evaluate possible catastrophic scenarios using consequence analysis methods. For this purpose, several

Wind tunnel investigation of the aerodynamic characteristics of five forebody models at high angles of attack at Mach numbers from 0.25 to 2 [PDF]
Five forebody models of various shapes were tested in the Ames 6- by 6-Foot Wind Tunnel to determine the aerodynamic characteristics at Mach numbers from 0.25 to 2 at a Reynolds number of 800000.

The mathematical theory of low Mach number flows [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2005 In this paper one can find a very interesting approach to the mathematical theory of the passage from compressible to incompressible fluid flows as the Mach number tends to zero. Starting from a system of equations which allows to treat simultaneously the three most commonly studied models: the isentropic incompressible Euler equations, the non ...
